Cov khoom siv ntau lawm thiab Precision Control Technology rau Nruam Basalt Fiber

1. Cov cuab yeej tsim khoom tseem ceeb rau kev txuas ntxiv Basalt Fiber ntau 
Tsis tu ncua basalt fiber ntau ntau lawm adopts "ib-kauj ruam txheej txheem", tus yam ntxwv los ntawm ib tug yooj yim workflow tab sis siab technical barriers. Piv nrog rau carbon fiber ntau lawm, txuas ntxiv basalt fiber ntau siv zog tsawg (tsawg dua 1/10 ntawm cov pa roj carbon fiber ntau lub zog noj) thiab tsis muaj CO₂, SO₂, lossis lwm cov pa roj carbon monoxide, ua rau nws muaj kev sib raug zoo rau ib puag ncig thiab qis carbon ntau lawm. Cov khoom siv thermal tseem ceeb rau kev tsim cov basalt fiber ntau yog lub cub tawg, uas tau muab faib rau hauv qhov cub hluav taws xob thiab lub tshuab hluav taws xob.

(1) Crucible cub
Lub cub tawg feem ntau ua haujlwm nrog ib lub qhov cub rau ib lub bushing.
Qhov zoo: Compact me me, tsis tshua muaj peev txheej, hloov tau yooj yim rau cov txheej txheem hauv cheeb tsam hloov kho, thiab tsim nyog rau cov khoom me me lossis cov khoom tshwj xeeb.
Disadvantages: Tsawg thermal efficiency, siab zog noj, khoom tsis zoo, tsis tshua muaj efficiency, thiab tag nrho cov nqi siab.
Tam sim no, crucible furnaces dominate lub nruam basalt fiber kev lag luam, nrog rau ib xyoos twg muaj peev xwm ntawm 100-300 tons. Vim yog electrode thiab refractory degradation, crucible furnaces muaj luv luv lifespan ntawm 6-12 lub hlis. Thaum lub sij hawm thaum ntxov ntawm kev lag luam kev loj hlob, crucible furnaces yog zoo tagnrho rau me me kev tsim khoom thiab cov khoom siv tshawb fawb.
Hom Crucible Furnaces:

• Nplaim Crucible Rauv: Rhaub los ntawm cov pa roj thiab cua combustion.
  Pros: Flexible nplaim tswj, ceev pib / nres muaj peev xwm.
  Cons: Tsis tshua muaj nplaim taws kub, tsis muaj peev xwm melting, lub zog pov tseg vim nitrogen (78% ntawm huab cua) tsim teeb meem NOₓ emissions, thiab cua kub tsis sib xws ua rau inconsistent melt homogeneity.
• All-Electric Crucible Rauv: Rhaub sab hauv ntawm phaj lossis pas nrig electrodes.
  Pros: High thermal efficiency, niaj hnub cua sov.
  Cons: luv lifespan vim electrode hnav, yuav tsum tau hloov tag nrho tom qab degradation.

(2) Tank Rauv
Raws li qhov kev thov rau fiber ntau thiab zoo zuj zus, tank furnaces (ib lub cub tawg nrog ntau lub bushings) tau dhau los ua qhov tseem ceeb rau kev tsim khoom loj. Lawv pab tswj qhov kub thiab txias, txhim kho yaj homogeneity, ruaj khov khoom zoo, thiab kev ua haujlwm siab, nrog rau txhua xyoo muaj peev xwm ncav cuag ntau txhiab mus txog kaum txhiab tons.
Hom Tank Furnaces:

• All-Electric Tank Rauv: Siv cov pas nrig electrodes (kab rov tav lossis hauv qab-mounted).
  Pros: High thermal efficiency thiab niaj hnub cua sov.
  Cons: Electrode hotspots, hnav tsis sib xws, thiab luv luv lifespan (~ 1 xyoo).
• All-Flame Tank Rauv: Rhaub los ntawm cov pa roj carbon monoxide nrog huab cua lossis cov pa ntshiab. Pure oxygen combustion yog nyiam rau kev ua tau zoo thiab txo qis emissions.
  Pros: Ntev lifespan (3+ xyoo), txuag hluav taws xob nrog cov pa ntshiab.
  Cons: Kub gradients nyob rau hauv sib sib zog nqus melts, txawm tias ntiav melts txhim kho uniformity.
• Hybrid Flame-Electric Tank Rauv: Muab cov nplaim hluav taws kub saum toj thiab hauv qab / sab electrodes.
  Pros: Enhanced yaj homogenization.
  Cons: Cov qauv tsim, tsis sib xws saum npoo cua sov, siab zog poob los ntawm cov dej txias electrodes, thiab luv lifespan vim electrode hnav.

(3) Bushing
Lub bushing, feem ntau yog ua los ntawm platinum-rhodium alloy, yog ib qho tseem ceeb rau kev tsim fiber ntau. Cov khoom loj loj xav tau cov khoom muaj peev xwm loj. Thawj bushings muaj 200 qhov; cov qauv tam sim no suav nrog 400, 800, thiab 1,200 qhov. Bushing thev naus laus zis nce qib kev sib koom ua ke nrog kev tsim kho lub tank rauv.

2. Precision Control Technology 
Basalt yaj nthuav tawm cov teeb meem xws li kev kub siab / crystallization, ceev ceev crystallization, nqaim txoj kev kub qhov rais, tsis sib xws fiber ntau hardening, muaj zog bushing wettability, thiab tsis zoo tshav kub transparency. Cov yam ntxwv no ua rau tsis muaj kev ruaj ntseg thaum lub sij hawm kos duab fiber ntau (xws li, tawg, flyaway, txoj kab uas hla variation). Stabilization nyob ntawm peb yam:

• Melt Homogeneity thiab Stability: Ua tiav los ntawm cov khoom siv raw khoom sib xyaw, ntsuas kub ntawm lub tshuab hluav taws xob, kev tswj qib yaj, thiab kev tswj xyuas siab.
• Bushing thiab Temperature Control: Ua kom cov bushing cua sov thiab tsis txhob crystallization.
• Kev Txhim Kho Cov Txheej Txheem Teeb Duab: suav nrog kev tswj xyuas meej ntawm kev kos duab nrawm, qhov ntsuas cua txias, thiab fiber ntau nro.

Cov thev naus laus zis tseem ceeb suav nrog kev tswj hwm qib siab rau cov khoom sib xyaw, qhov kub thiab txias, yaj theem, chamber siab, channel kub, bushing kub, thiab nqus ceev. Cov no ua kom ruaj khov, ua tau zoo tsis tu ncua basalt fiber ntau lawm.
